Turning a mobile phone into a One Time Password (OTP) generation device which can be used in the place of hardware tokens. Support for provisioning tokens using the KeyUriFormat and QR codes as well as manual creation. Can optionally be protected with a PIN to stop unauthorised access to the software tokens. Supports both HOTP (Event Tokens) and TOTP (Time Tokens) specifications.

Easily and securely keep track of all your Passwords! AuthPass is a stand alone password manager with support for the popular Keepass (kdbx) format. Store your passwords, share across all your devices and easily find them whenever you need to login.

Authnkey is a credential provider that lets you use FIDO2 security keys (like YubiKey, SoloKey, Nitrokey, or Token2) for passkey authentication on Android. Android's built-in WebAuthn support has a significant gap: it does not support CTAP2 over NFC. This means you cannot use PIN-protected passkeys or discoverable credentials with NFC security keys — you're limited to basic U2F tap-to-authenticate. Authnkey fills this gap by implementing the full CTAP2 protocol. The app registers as a credential provider, so any app or browser that supports the Android Credential Manager API will offer Authnkey as an option when passkeys are requested. This also works on devices without Google Play Services, since Authnkey implements the CTAP2 protocol directly rather than relying on Google's FIDO2 API. Supported features: - Passkey creation and authentication - PIN verification - Discoverable credentials - Multiple accounts per site - NFC and USB transports No root required.

The idea behind Authorizer is, to use old smartphones as a hardware password manager only. To avoid manual typing of long and complex passwords everytime you need them, Authorizer pretends to be an USB keyboard (e.g. over an USB On-The-Go adapter). With a button press inside the App, it will automatically enters the password for you on your pc, laptop, tablet or main smartphone.

DISCLAIMER: This project is developed solely for educational, security research, and personal investigative purposes. The author does not endorse or encourage any use of this software for unlawful or unethical activities. You are solely responsible for ensuring your use of this tool complies with all applicable laws and regulations. Bluetooth Low Energy (BLE) is a widely used wireless protocol that powers a huge variety of devices around you — from headphones, smartwatches, and fitness trackers to AirTags, IoT devices, game controllers, and even modern intimate gadgets. BLE devices communicate by broadcasting small packets of data, which can include device identifiers, metadata, and other information necessary for connectivity. These broadcasts, while essential for device functionality, can also be used to track your presence and movements. For example, a cheap pair of wireless headphones may expose a persistent identifier publicly. Anyone listening to BLE packets nearby — whether governments, companies, or malicious actors — could potentially use that information to track you without your consent. Fortunately, many modern devices implement privacy features in BLE to prevent tracking, such as randomized addresses and limited advertising. BLE Radar helps you distinguish between devices that protect your privacy and those that might be trackable. By analyzing BLE traffic in your surroundings, the app gives you insight into which devices are safe to use. Beyond analysis, BLE Radar can help protect you in real-time. The app can alert you when a suspicious device is nearby or if a device is moving with you over time, giving you an early warning against potential stalking or unwanted tracking. You can configure alerts based on device identifiers, types, or behaviors to fit your security needs. By making this app, the goal is to empower you with knowledge and control over the BLE devices in your environment. Understanding which devices are broadcasting trackable information and which are privacy-conscious allows you to make informed decisions about what you use, wear, and interact with daily. In general, the app is capable: * Scan, analyze and track Bluetooth devices around; * Create flexible filters for the radar; * Deep analysis of the scanned BLE devices, getting data from the available GATT services; * Gatt services Explorer; * Define the device type by metadata; * Define approximate distance to the device. Bluetooth Radar does not collect or send your personal or geolocation data. The project is fully opensource and available on GitHub.

Banana Split uses Shamir's Secret Sharing to split secrets into QR-code shards. Any majority of shards can reconstruct the secret — fewer reveal nothing. How it works 1. Enter your secret (e.g., a seed phrase, private key, password). 2. Choose how many shards to create and how many are required to reconstruct. 3. Use the auto-generated passphrase or enter your own. 4. Banana Split encrypts the secret with the passphrase, then splits the ciphertext into N QR codes using Shamir's scheme. 5. Print or save the QR codes. Write the passphrase by hand on every sheet. To reconstruct: scan a majority of QR code shards, enter the passphrase, and your secret is restored. Features • Offline — all cryptography happens on-device, no server communication • Save shards as PNGs or PDF with full Unicode font support • Camera and gallery QR scanning with multi-file import • Custom or auto-generated passphrases • User-selectable quorum (how many shards needed) • 7 languages: English, Russian, Turkish, Belarusian, Georgian, Ukrainian, Polish • Cross-platform shard compatibility with the Banana Split web app Security Encryption: scrypt key derivation + NaCl secretbox (XSalsa20-Poly1305). Splitting: Shamir's Secret Sharing over GF(256). No data collection, no analytics, no trackers. Web App Also available as a web app — no installation needed: https://nfcarchiver.com/banana/ Shards created in the app and web version are fully compatible. Open Source This app is a fork of banana_split by Parity Technologies, licensed under GPLv3. Source code: https://github.com/mezinster/banana_split

NOTE: This app requires shell access, which can be granted using either Shizuku or root. This application aims to create a unified internet quick-settings tile, which is actually useful (I'm looking at you, Android 12). Next to this, separate Wi-Fi and mobile data tiles are also available if you just want to go back to the behaviour of Android 11 or lower. Tapping the new unified internet tile will simply toggle between Wi-Fi and mobile data, which is exactly what I want it to do most of the time. This reduces the amount of taps needed from 3 (tap tile, disable wifi, enable data) to just 1 quick tap. In situations where you still want more control, long pressing the tile will redirect you to the relevant settings page.

Description BluePass extracts two factor authentication codes (2FA) from SMS and sends them to a paired device via Bluetooth RFCOMM. A Qt based companion app bluepass-server will receive the 2FA codes and provide them via the system clipboard. Use Case The company I work for is relying on third party services that require to authenticate using 2FA. The second factor is an SMS to your mobile phone. This app was built for convenience, to avoid having to unlock your phone, find the message and then type the received code on the PC. It is not about the time saved, it's about getting rid of robot tasks. Setup You have to configure parameters to match the sender of the SMS and parse the code from the messages sent to you. Currently, regular expressions are used for this task. However, a very basic setup will be provided below. Regular expression for sender has to be set to a regular expression that matches all the senders of SMS (as they appear in your chat application). Multiple numbers and names can be provided: To match CompanyA, you might simply putCompanyA into the box To match CompanyA and 12345678, write (CompanyA|12345678) Regular expression to filter the content has to be set to a regular expression that matches the messages you want to catch. Additionally, it has to define one group to extract the actual code that has to be sent to the PC. To match any number, you can use [^\d]*(\d+).* To match a code only with 6 digits, use: .*(\d{6}).* ... as the process of defining a proper regular expression is not that easy, there is another text box Test message. You can paste here the content of the SMS thatyou want to match and adjust the regular expression until it gets parsed correctly. The last step of the configuration is to pair with the bluetooth adapter of your PC and configure the adapter to be used. Operation Whenever your mobile phone receives an SMS (and the settings above are configured), this app will try to match the sender and content. If one of the two doesn't match, the message will not be processed any further. If the 2FA code could be extracted, a foreground service will be started (status bar) and the app tries to connect to the configured Bluetooth adapter and sends the code. It retries for some amount of time and reports the status in the status bar. Note: The notification in the status bar doesn't automatically disappear. However, this doesn't consume any resources and can be removed using the Stop button. If the code is required on the mobile phone, it can be copied using the Copy last button. Protocol The communication is based on very simple primitives using an RFCOMM channel. The UUID for the service is e4d56fb3-b86d-4572-9b0d-44d483eb1eee. Extracted codes are sent as text (over a secure Bluetooth connection) terminated with a new line character. Therefore, codes may not contain any new line characters. Future The protocol will be changed to something more sophisticated and extensible Configuration of the sender should be done through contact providers and not use regular expressions Allow to use this app to share text / files with the PC
